DISHWASHTNG MACHINE.

Application filed January 25, 1926. Serial No. 83,637.

This invention relates to new and useful improvements in dish washing machines and more particularly to this novel machine. The present invention constitutes an improvement over thatdisclosed in my pending applicationfiled in the United States PatentOflice on or about July 10, 1925, Serial No. 42,800. The main object of my invention is the provision of a dish washing 1 machine including in its construction novel means for remo lng foreign particles of matter from the washing fluid without draining the fluid from the tank of the machine or without stopping the operation thereof.

A further object of m invention is the production of a dish washing'machine of the character hereinafter .described wherein the washing fluid is directed from the bottom of the tank containing the same through a strainer and discharged back into the tank through the centrifugal force of the fluid. Other objects will appear hereinafter.

The invention consists in the novel fear tures of construction and combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings set- 9 ting forth the preferred form of construction and in which? Fig. 1 is a top plan view of the invention showing the preferred form of construction of the same,

zilpvention taken substantially on line 2-2 of s.

Fig. 3 is a vertical section view of the in: vention taken substantially on line 3-3 of Fig. 1, i v

Fig. 4 is a fragmentary section view of the strainer element embodied in the invention, and v V Fig. 5 is an enlarged fragmentary section 46' view of the invention.

' The washing machine illustrated in the drawings includes a .supporting base 1,

which has standards or legs 2 for supportthen placed in the chamber and the motor ing the base in spaced relation with respect to the surfaces upon which the machine is to be placed. The base 1 is provided with the upstanding flange 3 and mounted upon this base exteriorly of the flange. is a main body of the washer indicated at 4.

' The body 4 is provided with the bottom in paced relation with respect to. the base Fig. 2 is a vertical sectional view of thev 1 to form together with the upper portion of the body 1 a washing chamber 6. Extendlng upwardly through the bottom 5 and supported within the box 7 is the drive shaft 8 and arranged in the chamber 6 is the .basket support 9 which comprises the arms 10 and 11 arranged at right angles to each other as clearly illustrated in Fig. 1. The outer ends of the arms 10 and 11 are provided with upstanding retaining fingers 12 and resting upon the arms within the confines of the fingers 12 is the article containing' basket 13 comprising a wire frame 14 covered with screen mesh 15.

Arranged within the chamber 6 and attached to the inner walls of the body 4 are the breakwaters which comprise V-shaped plates 18 having flanges 19 whereby the plates may be readily secured to the body 4 with longitudinal ridges 19' positioned in spaced relation with the inside wall surfaces of the body, with the inclined walls of the V-shaped plates 18 disposed in longitudinal relation with a body.

At. diametrically opposite sides within the chamber 6 are the vertical flanges 20 which serve the same purpose as the V-shaped plates 18 but have the tendency to direct the fluid in a different path.

The shaft 8 extends into the housing 21 with its lower end mounted in a suitable bearing 22 and carries the gear 23 for meshing relation with the worm gear 24 on a shaft 25. The shaft 25 has a transverse arm 26 thereon bolted to a flexible disc 27 which is connectedto a motor shaft 28. The motor shaft 28 carries at its outer end a transverse arm 29 which is bolted to the disc 27 and arranged at, right angles to the arm 26 on the shaft 25., It will be apparent that by this-connection the usual noise through the connections between the motor drive gears will be eliminated.

It will be apparent from the foregoing description of the invention that in use the cover 31 is removed from the-top of the chamber 6 and the dishes or other articles placed in basket 13. The Washing fluid is 30 started for revolving the basket 13 in the chamber 6. It will be apparent that upon revolution of the basket 13, the washing fluid will be actuated in the same direction as the revolution of the basket'and upon this occurrence the washing fluid will have a. tendency to strike the incl ned faces of the and the description and disclosure of the the same will be 4 V-shaped plates 18 and the flanges 20, causmg the fluid to be directed inwardly through the basket. It will be apparent from this constant action of the washing fluid that thoroughly actuated through the articles placed in the basket so that the articles will be thoroughly cleansed.

The above description setting forth the washing machine proper is similar to the structure disclosed in my pending application for improvements in washing machine filed in the United States Patent Office on or about July 10, 1925, Serial No. 42,800,

washing machine inthe present application is set forth for theprincipal purpose of more fully understanding the present improvements therein.

As herein stated one of the objects of the invention is the provision wherein the washing fluid can be strained to remove foreign particles of matter therefrom without drain- Positioned in the outlet passage 43 andprojecting into said passage are the lugs v 46 that are diametrically opposed and in which the recesses 47'and 47 are provided. A strainer 48 is mounted in these recesses and has a rim portion 49 and a handleportion'50. Thelips on the lug 46 which define the recess 47 are longer than the lips which .define the recess 47". The strainer 48 rests on the bottom of the recess 47 but a clearance is present between said strainerand the bottom of recess 47, said strainer being retained by the long lips that define this recess. By gripping the handle 50 the strainer may be moved upwardly so as to contact with the bottom of recess 47, and

therefore the edge of the strainer that was v in the recess 47" will be out of contact with the lips defining this recess. When thus positioned the lower edge of the strainer may be tilted forwardly and then it is with-- drawn from the recess 47. The strainer may then be withdrawn from the passage 43 for the purpose of cleaning the same and removing accumulated foreign particles of matter.

The swelling action of the washing fluid caused by the rotation of the container forces the .fluid into the outlet opening where the fluid by reason of the centrifugal force is driven up the inclined passage through-the inlet opening back into the, tank, during operation of the machine. 'As' the fluid passes through the strainer 48 any foreign particles of matter are arrested thereby and prevented from passing with the fluid back into the tank.

It is apparent that the novel arrangement above described permits the continuous flow of fluid freefrom accumulated particles of matter over the dishes during cleansing thereof and that I provide a novel construction for separating the particles of foreign tical in use.

While I have shown and described the preferred form of my invention it is to be matter from the fluid which can be economically'manufactured and which will be pracunderstood that various changes and alterations in the same may be carried out during manufacture without departing from the spirit of theinvention or the scope of the appended claim.

The invention having been set forth what I claim as new and usefulis:-

The combination with a dish washer in cluding a fluid receiving tank, defining an outlet opening at. the lower end portion thereof and an inlet opening at the upper end portion thereof opposite the outlet opening, a basket adaptedfor the accommodation of a lu'r'ality of dishes and arranged insaid tankfor rotation, said basket .when ro tated being adapted to drive fluid in the tank by centrifugal force through the outlet' opening, of a housing associated with the tank and disposed on the exterior wall sur face thereof, said housing defining a passage opening communication between the outlet openlng and the mletjopenmg, a palrof diametrically opposed elements defined bysaid 'housingon the interior surface thereof providing opposite recesses, and astrainer member including a rim adapted for'confinement in said recesses. the diameter. of

said strainer member being less thanthe dimensional distance between the bottoms of said recesses permitting said strainer to be moved upwardly toward one of the recesses .115

to disengage the rim from engagement in the other recess when said strainer member is to be removed from;assoc1at1on.w1th the ion housing and in obstructing position with res'pectto the passage, and a handle member. associated with said strainer member facilitating removal of said strainer member.

In testimony whereof I aflix my signature.
